ASK A QUESTION What's the common way of saying "you're welcome" in Spanish?
Is there an idiomatic phrase or would I use a literal translation such as "tu eres bienvenido"?
"De nada", as stated, or "por nada", which is more like, "it was nothing".
"Con placer (with pleasure)" is always good as well. In our family though, it is a "de nada" fest.
"No hay de que" is pretty common. Sometimes I hear "tranquilo", meaning something roughly similar to "don't mention it."
In Costa Rica, if someone says "Gracias", you do not say "De nada".....no one says that.
Instead, we replace it with "Mucho Gusto" or "Con Mucho Gusto"
De nada, which literally means "of nothing".
"de nada" is the most common, but you can also say "con gusto" if you want to be a little more formal
Another phrase that is sometimes used (very similar to the answer that Calvo gave):
no hay porqué
Literally this means "there is no reason [to thank me]"
